Seat and crimp in two steps is my suggestion. The 300 XTP mag version is one of my favorites. Have had excellent luck over the years with it and its a very accurate slug! I used CCI when I couldn't find Remington primers. When I finally found Remington 7.5s, I bought enough I would never need more. I don't know that I can tell the difference in them though

My favorite load from my 7.5" FA ran that bullet at 1615 average.
